Abstract: 948,287. Electrolytically producing alkali metal chlorate. KREBS & CO. A.G. Nov. 13,1961 [Nov. 12, 1960], No. 40455/61. Heading C7B. Aqueous alkali metal chloride solution is electrolysed to produce alkali metal chlorate by passing the electrolyte between electrodes at an average velocity of at least 10 cms. per second and using a current density of at least 5 amps. per 100 sq. cms. The electrolyte leaving the electrodes is cooled and then recirculated. Fig. 1 shows a cell comprising an iron tank, anodes 14, metal or graphite perforate and imperforate cathodes 6 and 6a, an electrolyte supply 5 and cooling pipes 15. The upper part 9 of the tank has a corrosion resistant lining and is provided with a lid 11. The cathodes extend the full length of the tank and are secured, e.g. by welding, to the tank walls and are spaced from the anodes by not more than 10 mms. Cathode connecting clamps 8, Fig. 2, are provided on the tank walls. In operation, the evolution of gases at the electrodes causes the electrolyte to circulate as indicated in Fig. 1 past the cooling pipes 15. Fig. 4 shows a modification where circulation is aided by a pump 18. A sheet iron funnel 16 and a perforated plate 20 are also incorporated. The pump may circulate the electrolyte as shown or in the opposite direction. As an' alternative, the pump may be arranged above the electrodes. Fig. 7 shows an embodiment where electrolyte circulation is aided by bubbling additional gas through a pipe 22. Reference is made to an electrolyte storage tank for a group of electrolytic cells, the tank containing cooling means and the electrolyte from all the cells circulating through the tank. Sodium dichromate may be added to the electrolyte to form a membrane on the cathode surfaces which helps to suppress undesired cathodic reduction of alkali metal hypochlorite formed in the cell.

[Classes 78 (i) and 78 (iv).] A telescopic shoot resting upon coal &c. in a bunker &c. is shortened automatically when filled up to the feeding hopper or upper part of the shoot so as to permit the material to flow out at the lower end with minimum breakage. As shown in Fig. 1, wagons 7 are discharged by a tippler into a hopper 1 forming the top section of the shoot 2. The bottom section 3 is suspended by ropes 8, 10 from winding - drums 9 driven by a motor 11 through a solenoid clutch 13. A pivoted plate 15 is moved outwards by the material in the hopper 1 and operates a solenoid which releases a brake and moves the clutch into engagement or actuates a switch to start the motor. The section 3 is then raised until the level of coal in the shoot falls and the plate 15 resumes its normal position. The shoot is extended downwards by reversing the motor and operating the clutch by hand.

Projection type tube, Fig. 2e.-The target K of the tube comprises a layer of ferro-electric crystals which exhibit bi-refringence when bombarded by the electron beam f, thus modulating the light beam produced by the source M which passes through polarizers A, P and the plate Rt which on its near side comprises vertically arranged groups of coloured phosphors and which on its far side comprises a plurality of elemental lenses corresponding in number to the phosphor strips and each focused on the light source. The additional gun p<SP>11</SP> produces a dispersed beam of electrons F during the interframe period, thus creating a memory of the previous frame. S1-S8 and So comprise respectively a single set and a single wire as described with reference to Fig. 1 above.

Abstract: 1,175,568. Thermal switches. FR. SAUTER A.G. 13 Sept., 1967 [13 Sept., 1966], No. 41853/67. Heading H1N. [Also in Division F4] A boiler water deficiency expansion type safety device comprises an inner rod 1 arranged to operate a switch 6 and an outer tube 2, tube 2 having the higher coefficient of expansion and the rod 1 and tube 2 being heated by a coil 8 in insulation 9. Tube 2 is fixed at one end 3 to the switch case 5, and its other closed end is connected to rod 1. Under normal conditions, i.e. when tube 2 is immersed in the boiler water, and coil 8 is energized, rod 1 expands by a greater amount 10 since tube 2 is cooled by the boiler water, and the switch 6 is unoperated, as shown. When coil 8 is energized and there is a water deficiency, the temperatures of rod 1 and tube 2 rise since tube 2 is no longer immersed. Tube 2 expands by a greater amount, which cancels the amount 10, and an adjustable screw 11 thereby operates switch 6 to turn off the firing system and give an alarm. To check under normal conditions, coil 8 is de-energized and the temperatures of rod 1 and tube 2 fall. Rod 1 contracts more and amount 10 is cancelled and the switch 6 is operated.
